Iphepha le-Thermal liphepha elikhethekileyo eliphendula ngekhemikhali ukwenza umfanekiso xa ushushu. Isetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya ukuthengisa, iibhanki, ezothutho kunye nokhathalelo lwempilo.
Iphepha le-Thermal liqukethe iinxalenye ezimbini eziphambili: i-substrate yephepha kunye ne-coating ekhethekileyo. I-substrate yephepha ibonelela ngesiseko, ngelixa i-coating iqulethe inhlanganisela ye-leuco dyes, abaphuhlisi, kunye nezinye iikhemikhali ezisabela ngobushushu. Xa iphepha le-thermal lidlula kumshicileli we-thermal, inkqubo yokufudumala iqala. Umshicileli usebenzisa ukushisa kwiindawo ezithile zephepha le-thermal, ebangela ukuba i-chemical coating iphendule ngendlela yendawo. Yile ndlela yokusabela eyenza imifanekiso ebonakalayo kunye neetekisi. Imfihlelo ilele kwiidayi kunye nabaphuhlisi kwi-coating yephepha le-thermal. Xa kushushu, umphuhlisi uyasabela ukwenza umfanekiso wombala. Ezi dayi ngokuqhelekileyo azinambala kubushushu begumbi kodwa zitshintsha umbala xa zishushu, zenze imifanekiso ebonakalayo okanye umbhalo ephepheni.
Kukho iintlobo ezimbini eziphambili zephepha le-thermal: ukuhanjiswa ngokuthe ngqo kwe-thermal kunye ne-thermal. I-Thermal ethe ngqo: Ekushicileleni ngokuthe ngqo kwe-thermal, into yokufudumala yomshicileli we-thermal idibanisa ngokuthe ngqo nephepha le-thermal. Ezi zinto zokufudumeza ngokukhethayo zifudumeza iindawo ezithile ephepheni, zisebenze iikhemikhali kwindawo yokwaleka kwaye zivelise umfanekiso ofunekayo. Ukushicilelwa ngokuthe ngqo kwe-thermal ngokuqhelekileyo kusetyenziselwa izicelo zexesha elifutshane ezifana neerisithi, amatikiti kunye neelebhile. Ushicilelo lokudluliselwa kwe-Thermal: Ushicilelo lokudluliselwa kwe-Thermal lusebenza ngokwahlukileyo kancinci. Sebenzisa iribhoni eqatywe ngewax okanye intlaka endaweni yephepha elishushu elisebenza ngokuthe ngqo kubushushu. Abashicileli be-Thermal bafaka ukushisa kwi-ribhoni, kubangela ukuba i-wax okanye i-resin inyibilike kwaye idluliselwe kwiphepha le-thermal. Le ndlela ivumela ushicilelo oluhlala ixesha elide kwaye luhlala lusetyenziswa kwizicelo ezifuna ukufumaneka kwexesha elide, njengeelebhile zebhakhowudi, iilebhile zokuthumela, kunye nezitikha zemveliso.
Iphepha le-thermal lineenzuzo ezininzi. Inika ushicilelo olukhawulezayo, olukumgangatho ophezulu ngaphandle kwemfuneko yeekhatriji ze-inki okanye zetoner. Oku kuphelisa isidingo sokutshintshwa rhoqo kunye nokunciphisa iindleko zokusebenza. Ukongeza, ukuprintwa kwephepha le-thermal akulula ukucima kunye nebala, ukuqinisekisa ukufundwa kwexesha elide lolwazi oluprintiweyo. Nangona kunjalo, kubalulekile ukuqaphela ukuba ushicilelo lwe-thermal lunokuchatshazelwa yimiba yangaphandle. Ukuba sesichengeni ngokugqithisileyo kubushushu, ukukhanya, kunye nokufuma kunokubangela imifanekiso eprintiweyo ukuba iphele okanye ithobeke ngokuhamba kwexesha. Ngoko ke, kubalulekile ukugcina iphepha elishushu kwindawo epholileyo neyomileyo ukugcina umgangatho walo.
Isishwankathelo, iphepha le-thermal liyinto entsha ephawulekayo exhomekeke kwi-chemical reaction phakathi kwedayi kunye nomphuhlisi ukuvelisa imifanekiso kunye nesicatshulwa xa ibonakaliswe kubushushu. Ukusebenziseka kwayo ngokulula, ukuphumelela kweendleko kunye nokuqina kwenza kube lukhetho lokuqala kumashishini ahlukeneyo. Nokuba ngaba iirisithi zokuprinta, amatikiti, iilebhile okanye iingxelo zonyango, iphepha le-thermal lihlala liyinxalenye ebalulekileyo yeteknoloji yokushicilela.
